A liquid of volume 2.00 m3 and density 1.00 x 103 is mixed with 3.00 m3 of another liquid of density 8.00 x 103kg m-3. Calculate the density of the mixture [Assuming there is no chemical reaction]
A
5.20 x 102 kg m-2
B
1.13 x 103 kg m-3
C
8.80 x 102 kg m-3
D
5.20 x 103 kg m-3
Verified Correct Answer: D.
Physical Principles & Numerical Solution
\(V_T = 5m^3, m_1 = 2 \times 1 \times 10^3 = 2 \times 10^3\)
\(M_2 = 3 \times 8 \times 10^3 = 24 \times 10^3\)
MT = 26 x 103
D = \(\frac{m}{v} = \frac{26 \times 10^3}{5} = 5.2 \times 10^3\)
